Most of the comments were positive. I didn’t really see anyone go into detail
about how they used the tool, though.

I’m wondering if the teachers allowed their students to explore the tool or if
they used it as a presentation only.

I could use this activity in an elluminate session to review slope, rate, and
y-intercept. Most importantly the application would make it meaningful. It
would allow students to understand how each parameter affects the other as
well.
